With our VPD method (Vapor Phase Decomposition), we enable
- Reliable analysis of wafers and semiconductor components to a concentration range of 107 at/cm²
- Etching of the wafer surface with gaseous hydrogen fluoride (HF) to ensure absolute purity and safe handling of the HF gases.
- Collection of contamination and concentration in a small droplet using the PAD scan. This module offers various scan patterns, advanced handling of droplets, and preparation of the subsequent analysis.
- Preparation for the Analysis
